PHILIP JEHLE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO MARTIN NIXONAND WILLIAM H. NIXON, BOTH OF SAME PLACE.

FORMER FOR PAPER BAGS.

SPECIFICATION forming part of Letters Patent No. 329,173, dated October2'7, 1885.

Application filed December 2:2, 1884. Serial No. 150,976.

To all whom it may concern.-

Be it known that I, PHILIP J EHLE, a citizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented certainImprovements in Formers for Paper Bags, of which the following is aspecification;

My invention consists of a former, fully de scribed and claimedhereinafter, for creasing and folding a tube of paper prior toconverting it into a bag.

In the accompanying drawings, Figure 1 is a perspective view of myimproved former for paper bags; Fig. 2, an end view of the same lookingin the direction of the arrow; Fig. 3, a view illustrating the mode ofapplying a tube of paper to the former; Fig. 4, a transverse section ofthe tube when it is pressed to the sides of the former; Fig. 5, aperspective view illustrating the progress of the tube over the former;Fig. 6, a transverse section'of the tube after it has left the former;Fig. 7, a view of the tube distended, and Figs. 8 and 9 viewsillustrating modifications of my inven- "tion.

The former, which is shown most clearly in Figs. 1 and 2, consists of anoblong plate, A, and two vanes, a a, attached one to one side and theother to the opposite side of the plate, the whole being preferably madeof sheet metal. Each of the vanes is of triangular shape, the outer edgebeinginclined in respect to the plate and merging into the face of thelatter at m.

A tube, B, of paper to be converted into a bag is placed over thecruciform end of the former, as shown in Fig. 3, and as the tube ismoved in the direction of the arrow the paper is pressed against allsides of the plate A and its vanes a a, so that the tube temporarilyassumes the cruciform character shown in Fig. 4. As the movement of thetube is continued the portions which are pressed against the vanesgradually cease to be controlled thereby, and can be folded down, asshown in Fig. 5,

(No model.)

so that when the tube is withdrawn from the 5 former it will be in thefolded condition shown in Figs. 5 and 6.

WVhen the tube is distended, as shown in Fig. 7, it will be ofquadrangular shape, with a crease, indicated by a dotted line, on eachof its four sides, and will be ready for conversion into a square orsatchel bottomed bag.

While the above operation can be performed by hand, I propose toembodythe former in a machine by which the creasing of the tubes by theends of the former and the operations for completing the bag will beeffected automatically, this machine to be the subject of a separateapplication for a patent.

The former described above is intended for square bags, and the vanesare directly opposite each other. When a bag-blank of oblong section, asshown in Fig. 8, is required, the vanes are arranged out' of line witheach other, as shown in Fig. 9, and in order that the fornier may beadjusted for creasing tubes for bags either square or oblong in sectionI prefer to make the vanes laterally adjust-able on the plate A, thisopportunity for adjustment being effected in the present instance bymaking transverse slots h h in the plate and securing the flanged edgesof the vanes by bolts passing through the slots.

I claim 'as my invention- 1. The within-described former, the same 7 5,consisting of a plate, A, and triangular vanes combined with the plate,substantially as set forth.

2. The combination of the plate A with vanes a a laterally adjustable onthe plate, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence oftwo subscribing witnesses.

I PHILIP JEIILE.
